这只是部分信息，因为那个文件内容的却太长了，总共932289行，都是些看不懂的东东。
出了错，我肯定先看控制台下的这个异常是怎么回事吧。下面听我一一分析。我先百度了一下，看到了百度知道里有人提此问题，有最佳答案写到：

引起这种错误的原因很多，几点建议：
1、检查程序，优化数据库操作及SQL语句，如该关闭的数据库链接要及时关闭、查询语句该简化的简化；
2、检查网络状况，排除网络原因；
3、调整数据库配置参数，比如：会话超时时间、每秒最大连接数、最大连接数等等；
4、看看数据库的版本，有没有升级的可能，也许会解决这个问题；
      我心想之前一直用的这个版本oracle10G,版本10.2.0.1.0，代码也一直是这个代码，SQL自然也就自然是这个SQL，都没有此问题的出现啊，那就不应该是上述1、4的原因，我想寻找其他的解决方法，又点开了检索到的其他的网页，说的原因也大都说是SQL的问题或者数据库版本的问题，更有说是oracle8i,9i的bug，还有说是查了metaLink确定就是oracle的哪个哪个bug，BugID还写的清清楚楚，当然我也并不清楚metaLink是什么，我用的是oracle10G，而且才一年的时间，我当然更不敢怀疑这是伟大的甲骨文公司oracle的bug。于是考虑上述的原因2，不过也不大可能啊，因为出现这个以后，我还可以操作别的功能，那就证明数据库连接没有问题。
      于是，接着看网页，有说是驱动包的事（我的驱动是ojdbc14.jar），说是应该是getconnect的时候出的问题，连不上数据库，升级驱动包就可以了。有说是oracle回滚段设置的问题，有说是SGA设置的问题，还有说是表空间设置低的问题，还有说是oracle共享内存设置低的问题，还有说是数据库连接connect没有释放，还有说是PL/SQL版本的问题，PL/SQL5有此问题，我看了下我的PL/SQL的版本是7.1.1.1339，而且我又不是在PL/SQL里执行的SQL语句的时候报的这个错，也排除了这个因素。至于什么回滚段，SGA，我又不会设置。
     接着上Google继续寻找答案，因为百度我是不怎么完全相信的。从ITpub、ITEye、CSDN、CNOUR((China Oracle User Group))、DISCUZ(开发者乐园)、ChinaUnix....搜索答案，结果都跟上面差不多的，原因描述差不多，无非说是数据库的Bug，要升级数据库，或驱动包.....我实在不想是因为这个原因，我得怎么去说服我的领导，让他同意让我给去说服用户那是oracle的bug,然后给用户升级数据库。
     于是，我开始转移目光，不再只是搜索java.sql.SQLException: 无法从套接字读取更多的数据这个异常的答案。G了一下oracle日志文件报的那个错ORA-07445: 出现异常错误: 核心转储 [ACCESS_VIOLATION] [unable_to_trans_pc] [PC:0x7C34F937] [ADDR:0xCAA0000] [UNABLE_TO_WRITE] []，有人说是不需搭理oracle的这个ORA-07445，说是oracle经常有事没事抛这么个错，说不影响业务。我也的确是觉得虽然控制台抛了这么个错，但是数据删除是完全没有问题的。但是人用户提了这个问题啊，我总不可能去这么告诉用户吧。
     干脆不再找答案了。我注意到用户是使用我们的批量操作功能同时删除203360条数据，本来这个批量删除是做成，用户一点批量删除的时候，就出来一个进度条，并且采用了遮罩，在删除这203360条数据的过程中，用户是不能进行其他操作的，必须等待这些数据完全删除掉，页面重新刷数据，并提示批量删除成功的时候，才可以进行其他操作。但是被一个同事处理成，用户一点批量删除的时候，不出现那个进度条了，他觉得用户可以在删除203360这些数据的这几分钟里干点别的事，所以故意隐藏了那个mask。于是删除数据的请求是发过去了，后台也一直在删数据库里的记录，这时候页面上数据还没刷新（因为不可能给他做成实时刷新的），用户又进行了查询操作，相当于又向数据库发送了请求，而前面的delete 还没完且正在进行中，这又来了一个select......所以抛出了那个错。我试了一下，批量删除的时候，不去操作查询，控制台果然不报那个错了。我的问题算是告一段落了，但是这个异常到底是因为什么呢，众说纷纭，由他去吧......
